Safety-Related Shutdown With 3Rm11/3Rm13 Failsafe Motor Starters - Siemens 340 Manual

Description
3.5 Functions
Acknowledging
A malfunction is acknowledged by switching the control supply voltage back on and then
pressing the "TEST/RESET/RESET MODE" pushbutton.
Note
If a malfunction is repeatedly indicated, the 3RM1 motor starter is defective and must be
replaced.
Safety-related shutdown in the case of 3RM11/3RM13 Failsafe motor starters
Safety-related shutdown is achieved for the 3RM11 Failsafe and 3RM13 Failsafe motor
starters thanks to the special arrangement and checking of the switching elements. Safety-
related shutdown takes place when the control supply voltage is deactivated or by switching
off the control inputs. Malfunctions result in automatic shutdown. You will find additional
information in Chapter "Safety-related shutdown with 3RM11/3RM13 Failsafe motor starters
(Page 36)."
Display concept
The following events indicate the "Malfunction" status:
● DEVICE LED flashes red
● FAILURE LED shows a red light
● Fault signaling output active

Safety-related shutdown with 3RM11/3RM13 Failsafe motor starters

Safety-related shutdown of 3RM11/3RM13 Failsafe motor starters
In the case of the 3RM11/3RM13 Failsafe motor starters, safety-related shutdown takes
place by removing the control voltage (A1/A2). In the case of units with a 24 V DC supply
voltage, as an alternative safety-related shutdown can take place by removing the ON
command (IN1/IN2).
SILCL 3 to EN 62061, PL e/Cat. 4 to EN ISO 13849-1 can be achieved with both shutdown
methods. To achieve SILCL 3/PL e/Cat. 4 for the safety function, all components of the
safety function (detecting/evaluating/reacting) must be designed accordingly.
